Chrysanthemum plant named &#39;icon&#39;

ABSTRACT

A distinct cultivar of Chrysanthemum plant named ‘Icon’, characterized by its anemone-type inflorescences that are about 5.1 cm in diameter; attractive lavender purple-colored quilled ray florets and yellow green-colored disc florets; response time about 58 days; very freely flowering habit; dark green foliage; strong stems; and good postproduction longevity with inflorescences maintaining good substance and color for about two weeks in an interior environment.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum ×morifolium and hereinafter referred to by the name ‘Icon’.

[0002] The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Alva, Fla. The objective of the breeding program is to create new cut Chrysanthemum cultivars having inflorescences with desirable colors and good form and substance.

[0003] The new Chrysanthemum originated from a cross made by the Inventor in September, 1995, in Salinas, Calif., of the Chrysanthemum cultivar Pilar, disclosed in U.S. Plant Pat. No. 10,331, as the female, or seed, parent with a proprietary Chrysanthemum seedling selection identified as 0384, not patented, as the male, or pollen, parent.

[0004] The cultivar Icon was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Alva, Fla., in November, 1996. The selection of this plant was based on its desirable inflorescence color and good form and substance.

[0005] Asexual reproduction of the new Chrysanthemum by terminal cuttings taken in a controlled environment in Alva, Fla. since February, 1997, has shown that the unique features ofthis new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

[0006] Plants of the cultivar Icon have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

[0007] The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Icon’. These characteristics in combination distinguish ‘Icon’ as a new and distinct cultivar:

[0008] 1. Upright cut Chrysanthemum that is usually grown as a natural spray.

[0009] 2 Very freely flowering habit, about 12 inflorescences per flowering stem.

[0010] 3. Anemone-type inflorescences that are about 5.1 cm in diameter.

[0011] 4. Attractive lavender purple-colored quilled ray florets and yellow green-colored disc florets.

[0012] 5. Response time about 58 days.

[0013] 6. Dark green foliage.

[0014] 7. Strong stems

[0015] 8. Good postproduction longevity with inflorescences maintaining good substance and color for about two weeks in an interior environment.

[0016] Plants ofthe new Chrysanthemum are most similar to plants of the female parent, the cultivar Pilar. In side-by-side comparisons conducted by the Inventor in La Cej a, Antioquia, Colombia, South America, plants of the new Chrysanthemum had smaller inflorescences, shorter disc florets and a more yellow green disc florets than plants of the cultivar Pilar.

[0017] Compared to plants of the male parent, the seedling selection identified as code number 0384, plants of the new Chrysanthemum have smaller inflorescences and shorter disc florets. In addition, plants of the male parent and the new Chrysanthemum differ in inflorescence form as plants of the male parent have daisy-type inflorescences.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0018] The accompanying colored photographs illustrate the overall appearance of the new Chrysanthemum, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors ofthe new Chrysanthemum. The photograph on the first sheet comprises a side perspective view of a typical flowering stem of ‘Icon’ grown as a natural spray. The photograph on the second sheet comprises a close-up view of a typical flowering stem of ‘Icon’ grown as a natural spray.

DETAILED BOTANICAL DESCRIPTION

[0019] In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations and measurements describe plants grown in La Ceja, Antioquia, Colombia, South America, under conditions which approximate commercial practice in a single-layer polyethylene-covered greenhouse. Two-week old rooted cuttings were planted on Dec. 26, 2000 and received 14 long day/short nights followed by short day/long nights until flowering. Plants were grown as single-stem natural spray cut Chrysanthemums. During the production time, the following environmental conditions were measured: day temperatures, 20 to 27° C.; night temperatures, 8 to 13° C.; and light levels, 4,000 to 6,000 foot-candles. Measurements and numerical values represent averages for six to ten typical flowering stems and were taken about 9 to 10 weeks after the start of short days.
